This quirky arisaema hails from the regions of Nepal and Tibet. The name "exappendiculatum" means without a male appendage. It's still unclear if these were removed by area governments as a means of population control but nevertheless, we have a few to share. In growth habit, it is similar to Arisaema concinnum (slightly stoloniferous) with the wonderful whorled umbrella foliage atop 2' tall stems. For us, Arisaema exappendiculatum flowers in May with a nearly closed erect spathe...obviously embarrassed because it doesn't have a male appendage.
